A Chromecast is a digital media player developed by Google. The devices, designed as small dongles, can play Internet-streamed audio-visual content on a high-definition television or home audio system.
In speakers that have Chromecast build-in this device is build into the body of the speaker.
You can then control playback with a mobile device or personal computer through mobile and web apps that support the Google Cast protocol, or by issuing commands via Google Assistant.
